WEEDER.

Application filed June 1,

. whom it may concern:

no it known that I, ELSWORTH J. lVoNsnR,

on of the United States, residing at a, in the county of ll alla Walla and te ot llashington, hare invented certain new and useful improvements in lVeeders, of which t 1e following is a specification.

T is invenilon relates to tnat class of farm ts used for destroying weeds in 1215 for its object to provide a ose tianie is adapted to cutting members without stopdevicc and without dismounting provide a means my be manually oressure caused =s a partial rear elevation;

ig. o is a fragmentary view of a stop; and 6 shows a modified form of lifting cnanism.

-n the drawings like numerals refer to like parts throughout and the numeral 1 refers to the frame which consists of any desired material but shown in this case as of pipe.

On each end of the frame is a runner 2 which is tormea double to provide a space in which is positioned a cutting member 3 attached to and made a part of the cutting frame l. The double runner 2 may be of la meal as shown. but it is obvious that the runners may be of pipe similar to that or 7 e frame it cesired.

The cutting frame carries uprights 5 to which are pivotally attached hinge arms 6 and 6 "espectively, the forward arm 6 being provided ith bolt holes complemental to bolt holes in t c uprights 5, as plainly shown in Fig. ior aojustnient purposes. The hinge arm 6 is hinged to the rear portion oi. the frame l and is attached to the cutting frame low down so as to give a push directly against the cutting member 3. By this Specification of Letters Patent.

means the thrust comes below the center of support with a tendency to force the blade into the ground rather than draw it out.

(in each upright and projecting over the :"rainc 1 are steps 7 slidably attached thereto. These stops may be made yielding as shown 1 Fig. 5, it desired, although this is not deemed essentia the chain stop 7 shown in Fig. (3 being considered most practical.

in elevated cross frame 8 braces the frame 1 and carries a lilting mechanism consisting oi pulleys 9 over which is operably mounted a cable 1(),-one end oi which is attached to the cuttii irai'nc 4i; with its other end atto a foot lever 11 hinged to the frame 1 and with the outer end oi said foot lever provided with a foot pedal 12.

In modified form as shown in Fig. 6 the ii c ng mechanism is attached to the cross frame 55 and consists of rods instead of the cable 1 as a connecting medium between the loot lever 1 and the cutting frame 4. The foot lever is hiugcably attached to the cross frame in the manner shown and terminutes in a pc al 12 corresponding to the pedal 12 oi the above described lifting mechanism.

A platform 13 is rigidly attached to the frame 1 and is co vcniently located adjacent to the foot lever pedal. 12.

A second toot lever 14. is also hinged to the trans 1 and also carries a pedal 15 on its free end, its free end resting on and movable with the cutting frame. This lever is also positioned with its pedal conveniently located adjacent to the platform 13.

Kings 16 or any suitable means may be employed for dra'lt purposes.

In operation the driver stands upon the platform 13 and by forcing down the pedal 12 raises the cutting :lrame l until the cuting member 3 is tree of the ground; the inipenient is now in a condition of inoperation and may be transported withlit-tle effort.

It must here be understood that the term double runners (2). as here applied, and also as used in the claims,are intended to include wheels when such wheels are spaced apart to provide room for the vertical operation oi the cuttingmember :1. Y

it is obvious that a cutting member 3 of various lengths may be employed, as for instance an 8 foot frame may utilize a 6 foot utting member, or a 1!- ioot member by proing the member 3 feet on either end of ditional cost.

At the beginning of the work the pedal 12 is released and the cutting member enters the ground to a predetermined depth gaged by the position of the stop 7 on the uprights 5, (or 7" on the cross frame).

Now when heavy weeds are encountered the cutting member may become clogged with a tendency to raise out of the ground; to overcome this tendency the operator will stand on the pedal 15 forcing the cutting frame to remain in the ground against this tendency.

In cleaning the cutting member the operator places his foot on the pedal 12 (or 1%) and raises the cutting out of the ground, now

by referring to Fig. 2 the dotted lines rep resent graphically the position of the cutting member, and hinges, the cutting member being shown as elevated and with its cutting edge depressed, therefore it will be noted that the accunnilation of weeds on the cutting member will occur on the front or cut ting edge of the cutting member, and by raising the member in this manner the weeds will fall from the cutting member leaving it clean for further operation.

lis the cleaning operation is accomplished almost instantly it is unnecessary to stop the machine for this purpose.

If additional draft or suction of the cutting member is required it may be accomplished by throwing the top end of the uprights forward on the hinge arm 6 which may be carried out by means of the bolt holes above mentioned. 7

Thus I have provided a machine which is adaptable to all hints of ground, and one that may be readily cleaned without dismounting therefrom.

Having thus described my invention, I claim 1. In a weeder, in combination with a frame and runners thereof, a cutting frame hingedly mounted within said frame and suspended from the front and rear portions thereof, and carrying a cutting member, a stop attached to said cutting "rame, and a means for raising said cutting frame and with it said cutting member,

2. in a weeder, in combination with the frame and runners thereof, a cutting frame carrying a cutting member and adjustably and hing'edly mounted within said frame, a cross frame disposed on said frame longitudinally of the line of travel, and a means for elevating said cutting frame attached to said cross frame.

3. In a weeder, in combination with a frame and runners thereof, an adjustable, vertically operable cutting frame, hingedly mounted within said frame by hinge arms, a cutting member attached to said cutting f ame, the said hinge arms operating to depress the cutting edge of said cutting 1nemher as the cutting frame is raised, stops attached to said cutting frame, an elevated cross frame disposed. above said trame and longitudinal to the line of travel, an operating lever attached to and disposed beneath said cross frame, a means for connecting said operating lever operably with said cutting frame and a second lever hingeably attached to said frame and with its free end resting on and movable with said cutting frame.

in testimony whereof I aiiix signature.
